A Heavy Ion Monitor on a Chip Based on a Non-Volatile Memory Architecture -- Part II: Device Characterization & Modeling

Clayton Fullwood, Dale Julson, David Keltner, Hannah Lowrey, Mike Youngs, Tim Hossain

A non-volatile memory chip detects heavy ions by registering threshold voltage shifts that match detailed simulations.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Good agreement between simulated and experimental ΔV_th distributions was obtained. HIMoC was also shown to generate a signal that scales approximately linearly with a dose-like quantity proportional to ion fluence, LET, and active detector area.

C2weakest assumption

The assumption that heavy-ion energy deposition and secondary-electron effects can be adequately captured by Gaussian charge-loss profiles inside the DEVSIM model without additional free parameters tuned to the specific device or ion species (abstract, modeling workflow description).

C3one line summary

HIMoC devices produce threshold-voltage shifts from 24.8 MeV/u heavy ions that are modeled as Gaussian charge-loss profiles and scale linearly with fluence times LET times area.
